Raspberry Pi Education Kit used for SPI
- P1-19 (MOSI) --> 連接 LA's CH4
- P1-21 (MISO) --> 連接LA's CH2
- P1-23 (CLK) --> 連接LA's CH3
- P1-24 (CE0) -- > SPI Flash (MX25L4005A)
- P1-26 (CE1) --> CC2500 2.4G RF模組

是否要進行Channel更名 |
 |
套用SPI Protocol 進行分析後, 更方便通訊的狀況了才好Debug , 是否和DataSheet 的結果一致? |

這是程式執行的結果, 執行讀Flash ID 的動作, 和DataSheet 說明一致
The RDID instruction is for reading the manufacturer ID of 1-byte and followed by Device ID of 2-byte. The MXIC Manufacturer ID is C2(hex), the memory type ID is 20(hex) as the first-byte device ID, and the individual device ID of second-byte ID is as followings: 13(hex) for MX25L4005A.
